R-Kiem Seeds – “Preserving Legends, Cultivating the Future”
Where heritage genetics meet modern mastery.
Founded in 1998 in Spain, R-Kiem Seeds was born from a passionate collective of breeders, growers, and geneticists focused on preserving elite cannabis genetics. Their journey began with a mission: to safeguard rare and exceptional strains while crafting new hybrids that push the limits of cultivation and resin production.
Headquartered in Barcelona, the company emphasizes organic practices and artisanal care. Every seed is hand-packed and stored under controlled conditions, reflecting their obsession with quality and longevity. Over two decades later, R-Kiem has become a respected name in the global cannabis scene, known for its commitment to sustainability and breeder integrity.
